Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed February 20. 1907. Serial No. 358ut68.

To all whom it may concern: Be it known that I,- MARTIN ALBRECHT,v a 1 subject of the German Emperor, and a resi- 1 dent-of Friedber m the Grand Duchy of I i Hesse, Germanyjliaveinvented certain new i ing Motor Road-Vehicles and the Like, ol' which the following is a specification.

Thisinvention has for its object to proi vide vas elastic a drive as possible 'for three, 1 four, or more, wheels in motor road vehicles 1 and the like.

rMeans are alreadv known for driving more than two vehicle Wheels by means of by a petrol motor supplying current to the driving electro-motors.

The invention has for its object to provide a single means for transmitting both electhe vehicle thereby obtaining a material reanism.

The accompanying drawing illustrates an 1 example ofjthe ap lication of the invention to ve icles with our driving wheels. The working motors b of the vehicle may be 0on nected directlv with the armature a of an electric gear-clutch, The magnet frame of the electric gear-clutch can rotate and is di-- rectl connected to the differential (i, from wheels 2 andf for instance. It is obvious that the armature and magnet frame can always be exchanged one for the other and pensed with by arranging two electric gear clutches andconnecting each with one of the as the armature a rotates in the magnetic field, electric currents are pro.

duced' in the armature in accordance with the theory oi dynamo electric machines. These currents are then transmitted to mo tors m and n driving the front wheels 9 and ii.

If more than four wheels are to be driven, this can be effected by arranging a greater number of motors, or electric gear-clutches, or of both motors and electric gear-clutches. As current is being taken from the electric gear-clutch, the magnet frame tends to rotate and to transmit work to the wheels connected to it.

( laim:

'1. in a motor car, the combination of a plurality of independent driving wheels, a prime motor I), an electric generator, differential gearing connected with one element of said generator, and with-two of the driving wheels, and. electric motors adapted to be energized by said generator and arranged to driveothers of saidwheels.

2. In a motor car, the combination of two parallel axles, a plurality of driving wheels independently mounted on each axle, a prime motor I), an electric generator, a differential gear mechanically connected with one member of said gei'ierator, means mechanically connecting said gearing with the wheels on one axle, andclectrically operated means in circuit with said generator and adapted to drive the wheels on the other axle.

In testimony whereof l. have signed my name to this specification in the presence of two subscribing witnesses.
